A TV Program Discovery Dialog System using recommendations

We present an end-to-end conversational system for TV program discovery that uniquely combines advanced technologies for NLU, Dialog Management, Knowledge Graph Inference and Personalized Recommendations. It uses a semantically rich relational representation of dialog state and knowedge graph inference for queries. The recommender combines evidence for user preferences from multiple modalities such as dialog, user viewing history and activity logs. It is tightly integrated with the Dialog System, especially for explanations of recommendations. A demo of the system on a iPad will be shown.
